I just wanted to start a new typescript project using webpack5 and webpack-cli. In my surprise I'm getting these errors:

So it turned out I had to change tsconfig
option include
to specify the directory which typescript will analyse.
According to documentation on include option the default value is:
[] if files is specified, otherwise ["**/*"]
So the default behavior is to analyse all repository including node_modules
.
To sum up just edit include attribute to include only the src folder:
{
"include": ["src/**/*"]
}
